The distribution maps were produced for the Distribution Mapping and Analysis Portal (DisMAP) project. The distributions were generated from catch-per-unit-effort data from the fisheries bottom trawl surveys. This data set covers 7 regions of the United States: Northeast, Southeast, Gulf of Mexico, West Coast, Eastern Bering Sea, Aleutian Islands, and Gulf of Alaska. These data were created as part of the DisMAP project to enable visualization and analysis of changes in fish and invertebrate distributions. These interpolated biomass layers provide information on the spatial distribution of species caught in the NOAA Fisheries bottom trawl surveys. Information on species distributions is of paramount importance for understanding and preparing for climate-change impacts, and plays a key role in climate-ready fisheries management. The distribution maps were produced by NMFS OST in partnership with OceanAdapt at Rutgers University underDevelopment Karp, Melissa A (301) 427-8202 melissa.karp@noaa.gov pointOfContact Haverland, Timothy J 301-427-8137 301-713-4137 1315 East West Hwy Silver Spring MD 20910-3282 USA tim.haverland@noaa.gov custodian annually EARTH SCIENCE > BIOSPHERE > ECOLOGICAL DYNAMICS > SPECIES/POPULATION INTERACTIONS > RANGE CHANGES EARTH SCIENCE > OCEANS > AQUATIC SCIENCES > FISHERIES climate change distribution fish fishery-independent surveys invertebrates seasonal distribution theme Aleutian Islands Eastern Bering Sea Gulf of Alaska Gulf of Mexico Northeast US Southeast US West Coast place DOC/NOAA/NMFS/OST > Office of Science & Technology, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
